Solar – the road unexplored

India continues to champion solar power in its future plans of a 500 GW non-fossil fuel energy installation target for 2030. One major challenge is the procurement of suitable land free of socioecological constraints for renewable energy capacity. An innovative solution is the integration of solar PV systems either along the side of roads or above (highway solar) or directly on their surface (on-road solar). These approaches have the potential to be utilized on all national highways and expressways.
